Error 1330.A Install Error CorelDraw X3

I have purchased a new laptop, running Windows 7.  I went to reinstall my CorelDraw X3 and I received the following box with error:

Error 1330.A file that is required cannot be installed because the cabinet file f:\CGS13\DrPP.cab has an invalid digital signature.  This may indicate that the cabinet file is corrupt.

I saw some said it could be my antivirus.  I unstalled Norton and stll no luck.  Any help!!!
